Post-Contractual Remedy

A post-contractual remedy is any form of legal relief pursued after the contracting authority and the winning supplier have signed the contract. At that point, the practical options available to an unsuccessful tenderer are substantially narrower than those available during the standstill period, and the chances of changing the actual outcome of the procurement are considerably lower.

What is a Post-Contractual Remedy?

Once a contract is signed, the default remedy in most European legal systems is a claim for damages. A successful damages claimant does not receive the contract: they receive financial compensation for the loss they suffered as a result of the unlawful award. This typically means the estimated profit they would have made had they been awarded the contract, discounted by the probability that they would actually have won. Proving and quantifying this loss is frequently the most difficult part of any procurement litigation.

However, the Remedies Directive (2007/66/EC) created a more drastic post-contractual remedy: the declaration of ineffectiveness. Where a contracting authority commits certain defined serious breaches (such as awarding a contract without prior publication of a notice, or signing during the standstill period in a way that prevented effective pre-contractual challenge), the review body must declare the contract ineffective. Ineffectiveness unwinds the contract: it is treated as void from a future date, and the parties must unwind obligations already performed.

Where ineffectiveness would be disproportionate given the public interest in contract performance, review bodies may instead impose alternative penalties such as financial fines on the contracting authority or a shortening of the contract duration.

In the UK, the Procurement Act 2023 retains the ineffectiveness sanction and the damages remedy for post-contractual challenges.

Why Post-Contractual Remedies Matter for Bidders

Post-contractual remedies are a fallback, not a first choice. A bidder who misses the standstill period or who discovers a procurement error only after the contract is signed must rely on damages, which are uncertain, expensive to litigate, and take years to resolve.

That said, post-contractual claims are sometimes the only viable route. A bidder may not become aware of a procurement irregularity until after the contract is signed and the competitor begins delivery. Or the irregularity may be of a type (such as collusion between the authority and the winning supplier) that was concealed and only comes to light through disclosure in litigation. In those cases, a damages claim (procurement) is the appropriate remedy.

Example

A Swedish technology company loses a public sector cloud services contract. They do not challenge during the standstill period because the scoring looked superficially reasonable. Six months into the contract, documents released under a freedom of information request reveal that the evaluation panel included an individual with a financial interest in the winning supplier. The Swedish company brings a damages claim (procurement) in the administrative court, arguing that the conflict of interest rendered the evaluation unlawful and caused them a loss of profit.

Frequently Asked Questions

Is a post-contractual damages claim worth pursuing?

It depends on the value of the contract, the strength of the evidence, and the litigation costs. Damages claims in procurement cases are complex: the claimant must prove that the breach occurred, that they would have won but for the breach, and what profit they would have earned. Expert evidence on tender pricing and probability of success is usually required. For high-value contracts with clear evidence of irregularity, a claim can be economically justified. For lower-value contracts, the litigation cost often outweighs the potential recovery.

Can a bidder seek both a pre-contractual remedy and post-contractual damages?

Yes, in principle. A bidder who challenges during the standstill period may seek suspension of the contract signature and, as a fallback, damages if the suspension is lifted and the contract proceeds. If the pre-contractual remedy fails and the contract is signed, a parallel damages claim may continue.

How long do bidders have to bring a post-contractual claim?

Limitation periods vary by jurisdiction. In the UK, the Procurement Act 2023 sets specific time limits for bringing proceedings, generally linked to the date of knowledge of the breach. In EU member states, the limitation periods applicable to procurement damages claims are determined by national law, typically ranging from 1 to 5 years from the date when the claimant knew or should have known of the breach.
